Review of Safety and Efficacy of Polmacoxib: A Novel Dual Inhibitor of Cyclo-oxygenase 2 and Carbonic Anhydrase in Osteoarthritis and Acute Painful Conditions.

Osteoarthritis (OA) is a chronic degenerative joint disorder and a leading cause of pain and disability among the elderly. Traditional nonsteroidal anti-inflammatory drugs (NSAIDs), though effective in symptom relief, pose significant risks of gastrointestinal, cardiovascular, and renal complications, especially in long-term use. Polmacoxib (CG100649) is a newer NSAID with its dual inhibitory role on cyclooxygenase-2 (COX-2) and carbonic anhydrase (CA), planned to offer higher therapeutic efficacy and safety. This review critically examines the pharmacodynamic and pharmacokinetic properties of polmacoxib, along with its clinical efficacy and safety in OA and acute pain conditions. Clinical trials across phases I-III consistently show polmacoxib to be well tolerated and effective in pain relief and efficient improvement of the joint, with a safety profile comparable to or better than traditional COX-2 inhibitors like celecoxib. Recent trials also explore its role in combination therapies for acute pain management, including dental and postoperative settings, showing noninferiority to standard regimens and fewer adverse events. Its innovative mechanism and pharmacological profile support its potential as a next-generation NSAID for OA and pain management, particularly in populations at high risk for NSAID-induced adverse effects. Further larger long-term studies are warranted to confirm its medical benefits and broader therapeutic applications.
